Abstract

An adhesive composition of at least one ethylene polymer or copolymer, wherein at least one first polymer or copolymer including the unsaturated carboxylic acid ester type comonomer is copolymerized in a continuous high-pressure tubular reactor, while a second polymer or copolymer including the functional comonomer is copolymerized by either autoclave or tubular continuous high-pressure radical means; the first and second polymer or copolymer possibly being of one and the same polymer/copolymer. Also, a multilayer structure that incorporates the adhesive composition and a particular process for obtaining this composition.
